Second solution could be done using a MAXIM transceiver (MAX218) In this case the
compliance with RS232 (+-5V) is possible.

Another level adapting method could be done using a standard RS232 Transceiver
(MAX3237EAI) adding some resistors to adapt the levels on the GE865 Input lines.

NOTE: In this case has to be taken in account the length of the lines on the application
to avoid problems in case of High-speed rates on RS232.

The RS232 serial port lines are usually connected to a DB9 connector with the
following layout:
